“You know, I was thinking about what Bishop said. About... What do you think out legacy is gonna be? When we're gone, I mean, after all the stuff we've done, you think folks will remember us? You know, like, a hundred years from now?”
Dean makes this statement at the end of “The Memory Remains,” and it has profound meaning. We all want to be remembered. We all want to know that over time---after we're no longer here---that we'll have left something behind that people will remember us for. It's human nature. We seek to find that meaning of life and need to build up our legacies. We all want to be the one that says proudly “Kilroy Was Here.” However, no matter how much money we make, no matter how many experiences we have, no matter the prestige we earn, at some point, we will die and there will only be fleeting memories left behind.
And so, Sam answers his question by stating, “Well, I mean... guys like us, we're not exactly the type of people they write about in history books, you know? But the people we saved, they're our legacy. And they'll remember us and then I guess... we'll eventually fade away, too. That's fine, because we left the world better than we found it, you know.”
